MOUNT JOHNSON. 
ANNOTATED GUIDE. 
Altitude 58-5 ft. (17-8 m.)—Leaving Bona- 
venture Station by the 
Grand Trunk Railway 
the train crosses the St. 
Point St. Charles. Lawrence river on the 
Jubilee bridge. This 
bridge was built to replace the old Victoria 
bridge designed by Stevenson.  Itis 9,184 feet 
in length, being one of the longest bridges 
in the world. 
From the bridge a very fine view of the city 
of Montreal is obtained. 
The railroad passes over the great plain of 
the St. Lawrence low- 
lands underlain here 
by nearly horizontal 
strata of Ordovician 
age. The plain is 
mantled by duiift of 
no great thickness. 
In its present form it 
represents the sea bot- 
tom of the glacial estuary of the St. Lawrence 
laid bare by the retreat of the ocean at the 
close of the Glacial age. 
The train here crosses the Richelieu river, 
a tributary stream which enters 
the St. Lawrence at Sorel. It 
is an industrial centre with 
large pottery works, silk factory, etc., and 
a military post with Infantry school. 
The Richelieu in early times was called 
Riviére des. Iroquois 
Iberville Junction. because the war par- 
ties of the Mohawk 
Indians came up by 
it from the south when 
making their raids upon the settlements in 
the St. Lawrence valley. The English and 
French aimies traversed it incessantly during 
Montreal.
